ANTISKIDDING APPARATUS.

Application filed November 26, 1923. Serial No. 676,996.

To all whom it may concern.

Be it known that I, AUeUsrA S. JOHNSON, a subject of the King of Sweden, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Antiskidding Apparatus, of which the following is a specification.

This invention relates to antiskidding apparatus for vehicles, and has for one of its objects to discharge a quantity of sand or other gritty material, in front of the wheels, so that the. same may take a firm hold upon wet and slippery pavements for the purpose of preventing skidding of the vehicle.

Another object is to provide mechanism for discharging sand or the like at will of the driver of the vehicle.

A still further object is to so adapt the apparatus that a. single control will take care of the discharge of the sand to either all of the wheels, by providing suitable branch outlets, or to one or twowheels by providing individual devices, as desired.

Further objects consists in the simplicity of construction and other details which are set forth more fully hereafter and illustrated in the accompanying drawing in which Fig. 1 is a sectional view through a preferred form of the sand receptacle, showing the control of the discharge mechanism by foot pressure, and the discharge nozzle of the device in front of a wheel which is shown diagrammatically only.

Fig. 2 is a vertical cross-sectional view of the sand receptacle, taken along the plane of line 2-2, in Fig. 1.

Fig. 3 is a horizontal cross-sectional view taken along the plane of line 3-3 in Fig. 2; and

Fig. 4 is a sectional View of part of the vehicle showing a modified form of control, operable by hand.

Like characters of reference denote similar parts throughout the several views and the following specification.

is an oblong, box-like, receptacle, having a hinged top cover 11. 12 is a slide-like valve member, at the inner bottom of receptacle 10. Valve 12 is provided with an upwardly turned flange 13 and a discharge opening 14. The bottom of receptacle 10 has, in rear of slide valve 12, a box-like compartment 15, preferably open at its bottom, within which the flange 13 of the valve is free to slide. A valve rod 16 is attached to the flange 13 and passes through a rear wall 17 of box 15. A spring 18 is placed around valve rod 16, abutting against, respectively, the rear wall 17 and a front wall 19 of boX 15, this spring having the tendency to press the flange 13 of the valve. against the said front wall 19. 20 and 21 are guides within the receptacle 10, at its bottom, and at both sides of the valve 12, for the purpose of directing the motion of the valve. Receptacle 10 is provided at its bottom with an outlet nipple 22, over which is placed a T connection'23, to both ends of which are fastened flexible pieces of hose, tubing or the like 24 which terminate in nozzles 25, adapted to discharge the sand or other gritty material in front of the wheel, as shown in Fig. 1.

26 is a lever near the drivers seat within the vehicle, pivoted about a fulcrum 27, supported by a bracket 28. Lever 26 has one end projecting into the drivers compartment which end is pedal shaped at 29 to make the same easily operable by foot pressure. Another end 30 projects below the bottom wall of the drivers compartment, and has fastened to it a cord or cable 31 which connects to the outer end of valve rod 16.

In the modified form of control, shown in Fig. 4, a bracket 32 with a roller 33 is fastened to the underside of the drivers compart-ment. Cable 31 is passed over roller 33 and is led over another roller 34 held by a similar bracket 35, fastened to the upper inner front wall of the drivers compartment. 36 is a handle attached to the end of cable 31 hanging over the roller 34.

The operation of my device is, as follows:

Sand or any other gritty material is placed within the receptacle 10. In case it is necessary to use the device, the driver will either press pedal 29 forward or, in case of hand control, pull down handle 36 which will pull out the slide valve 12 and bring opening 14 of the Valve in register with outlet nipple 2-2 of the receptacle, allowing sand to be discharged therefrom. From the outlet nipple 22 the sand passes by way of T connection 23 into flexible tubes 24, and is then discharged by nozzles 25 in front of the j 1 sure on either the foot pedal 29 or handle S6 is released, spring 18 will automatically return the valve 12 to closed position.

The device is particularly applicable to vehicles which do not run in tracks and which are likely to skid on slippery, wet or icy pavements, such as for instance automobiles or motor trucks. In such cases the receptacle may be mounted at the lower front end of the radiator, resting with its sides on the front springs of the machine, or it may be mounted at the rear, near the gasoline tank, or at the running board, or at any other convenient place. Furthermore, while I have shown the device provided with 2 outlets, if preferred 4- could be provided by again branching each outlet of the T shown, or 2 or more individual valves may be used in the receptacle, each controlling an individual outlet, and all valves connected to the pedal or handle, as the case may be. Or, if preferred, 2 or more receptacles may be provided, the valves of which are controlled by one pedal or handle, as described.

Many other changes may be made in the detail construction of the valve, for instance, each of which may be provided with 2 or more springs, if desired, of other shape than shown, or, each valve may be provided with several outlet openings adapted to. register with corresponding outlets in the receptacle.

The device is susceptible to various: modifications in the form, proportion and minor details of construction which may be resorted to Without departing from the principle or sacrificing any part of the invention, as defined in the appended claim.

lVhat I claim as new, is:

In an antiskidding device for vehicles, a receptacle for gritty material, having a substantially fiat bottom with outlets therein and a box shaped recess, conduits from the said outlets to discharge the said material in front of wheels of the vehicle, a valve slidingly arranged within the receptacle and having openings to register with the said outlets when in open position, the said valve having an upturned flange adapted to slide Within the said recess at the bottom of the receptacle, and an operating rod attached to the said flange and projecting through the said recess and out of the receptacle, a compression spring surrounding the said op erating rod, having one end pressing against the said flange and its other end against an opposite wall of the said recess, and means, remote from the said receptacle, to operate the said valve.

In testimony whereof I have hereunto set my hand and seal in presence of two subscribing witnesses.
